Study on the Sterilization Process of Tilapia Fillets with Acidic Electrolyzed Water

The purpose of this article is to optimize the sterilization process of tilapia fillets with acidic electrolyzed water and develop a novel bacteria reducing pretreatment method for tilapia fillets.The effects of acidic electrolyzed water sterilization method,oxidation-reduction potential (ORP),sterilization time and material-liquid ratio on tilapia fillets were investigated.Single factor and orthogonal array design methods were used to optimize sterilization process,and hydrogen peroxide was used as a control to evaluate the sterilization effect of acidic electrolyzed water and its influence on the sensory and texture of tilapia fillets.The results showed that the optimal sterilization process for tilapia fillets was achieved under following conditions:soaking method,ORP 1163 mV,sterilization time 6 min,material-to-liquid ratio 3:80.Under these conditions,the sterilization rate of tilapia fillets reached 98.0%.The sterilization rate of acidic electrolyzed water on tilapia fillets was significantly higher than that of hydrogen peroxide (P<0.05).Acidic electrolyzed water can maintain the original color and texture of tilapia fillets.
